Answer 1

Answer:

$\huge\sf\red{50 \: days}$

Explanation:

( 150 students)×(60 days)= total food eaten.—(1)

Now there are 150+30 students.

So,

(180 students) × (x days)= total food eaten.—(2)

From eq.1 and eq.2,

$(180 \: students) \times (x \: days) = (150 \: students) \times (60 \: days)$

$x \: days = \frac{150 \times 6}{180}$

$x \: days = \frac{9000}{18} = \frac{100}{2}$

$x = 50 \: days$
